4x+4-2=5\left(x+4\right)
Use the distributive property to multiply 4 by x+1.
4x+2=5\left(x+4\right)
Subtract 2 from 4 to get 2.
4x+2=5x+20
Use the distributive property to multiply 5 by x+4.
4x+2-5x=20
Subtract 5x from both sides.
-x+2=20
Combine 4x and -5x to get -x.
-x=20-2
Subtract 2 from both sides.
-x=18
Subtract 2 from 20 to get 18.
x=-18
Multiply both sides by -1.
